South of the plume, a wave pattern appears. Both airborne dust and clouds can make waves in the atmosphere visible to satellite sensors. The northern portions of these waves are faint, but as they meld with cloud formations in the south, the waves become easier to discern. Just north of the waves, the ocean water takes on a pale green color, which may be due to shallow water, sediment and/or algae.
